What does it do? A complete logical expression log_exp can be placed in parentheses in order to define the priority of processing. log_exp can be a combination of multiple expressions using AND, OR, or EQUIV or a logical expression negated using NOT . A logical expression in parentheses is itself a logical expression. BEGIN_SECTION SAP_INTERNAL_HINT Undocumented feature: The space before the closing bracket can be omitted if the last operand is a text literal within quotes. END_SECTION SAP_INTERNAL_HINT
Latest notes: The smallest unit of a logical expression that can be placed in parentheses is a relational expression. NON_V5_HINTS ABAP_HINT_END
ABAP_EXAMPLE_VX5 A combination of the following logical expressions NOT log_exp1 OR log_exp2 AND NOT log_exp3 AND log_exp4 EQUIV log_exp5 can be parenthesized explicitly as follows to stress the implicit parentheses: Parentheses around the expressions with NOT ( NOT log_exp1 ) OR log_exp2 AND ( NOT log_exp3 ) AND log_exp4 EQUIV log_exp5 ABAP_EXAMPLE_END Parentheses around the expressions with AND ( NOT log_exp1 ) OR ( log_exp2 AND ( NOT log_exp3 ) AND log_exp4 ) EQUIV log_exp5 Parentheses around the expressions with OR ( ( NOT log_exp1 ) OR ( log_exp2 AND ( NOT log_exp3 ) AND log_exp4 ) ) EQUIV log_exp5 Parentheses around the expressions with EQUIV ( ( ( NOT log_exp1 ) OR ( log_exp2 AND ( NOT log_exp3 ) AND log_exp4 ) ) EQUIV log_exp5 ) Changing the parentheses explicitly changes the meaning of the expression. For example, if explicit parentheses are set as follows in the expression above ( NOT log_exp1 OR log_exp2 ) AND NOT ( log_exp3 AND log_exp4 EQUIV log_exp5 ) the expression looks as follows after implicit parentheses are set: ( ( ( NOT log_exp1 ) OR log_exp2 ) AND ( NOT ( ( log_exp3 AND log_exp4 ) EQUIV log_exp5 ) ) )
